Check Digit Verification of cas no
The CAS Registry Mumber 261720-27-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,7,2 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 261720-27:
(8*2)+(7*6)+(6*1)+(5*7)+(4*2)+(3*0)+(2*2)+(1*7)=118
118 % 10 = 8
So 261720-27-8 is a valid CAS Registry Number.
